I'm working on my second quilt, have the top done, and spent several hours yesterday marking it with my stencil & ruler & sewline pencil... and today I'm a bit sore from how I was sitting, hunched over. What I would like to know is where do you do your marking, how high is your table (if you use one) or workspace, what works for you, what doesn't?
TIA - Betsy

Depends on the pattern I'm marking. If it's an all-over pattern I generally do it on my cutting table. Otherwise I mark as I go, just put a hard surface underneath my sandwich - either in/out of the hoop. But that's handquilting. Not sure how you'd mark in sections for machine quilting. Just take breaks and stretch as others have suggested.
